Problems solved by technology

[0003] With the development of technology and the intensification of market competition, the cost requirements of products are getting higher and higher. Among them, the cost of FPC is estimated according to the typesetting area. The structure of the FPC is continuously improved. For example, the FPC body and the lead-out end are connected separately, which can increase the number of FPC arrangements. However, the setting of this structure makes it necessary to weld the FPC body and the lead-out end together when the FPC is used, which increases a production process. process, which increases labor costs

Embodiment 1

[0030] Such as figure 1 As shown, a backlight FPC provided by the embodiment of the present invention, the FPC includes a ring-shaped FPC body 1 and a lead-out 2 drawn from the FPC body 1, the lead-out 2 and the FPC body 1 are integrally formed in the present invention, Higher reliability. At least one pair of symmetrical LED lamps 3 are arrayed on the FPC body 1 , and each LED lamp 3 is welded on the FPC body 1 through a pair of pads with a certain distance. Such as Figure 4 As shown, the lead-out terminal 2 is connected to the main board 4 of the display device, and the circuit is connected to make the LED light emit light, thereby providing a backlight for the display device. The connection method between the lead-out end 2 and the main board 4 is preferably but not limited to welding or plugging.

[0031] Such as figure 2 As shown, as a further improvement, the interior of the FPC body 1 is hollow, and the lead-out end 2 surrounds the FPC body 1 and is formed in the ...

Embodiment 2

[0034] Such as figure 1 As shown, a backlight FPC provided by the embodiment of the present invention, the FPC includes a ring-shaped FPC body 1 and a lead end 2 drawn from the FPC body 1, and at least a pair of symmetrical LED lamps are arrayed on the FPC body 1 3. Each of the LED lamps 3 is welded on the FPC body 1 through a pair of pads with a certain spacing. Such as image 3 As shown, the lead-out terminal 2 is connected to the main board 4 of the display device, and the circuit is connected to make the LED light emit light, thereby providing a backlight for the display device. The connection method between the lead-out end 2 and the main board 4 is preferably but not limited to welding or plugging.

[0035] Such as image 3 As shown, as a further improvement, the lead-out end 2 is arranged around the outer area of ​​the FPC body 1, which can save materials for FPC production and reduce the volume of the FPC.

[0036] Further, the FPC body 1 can be hollow ring-shaped ...

Abstract

The invention discloses a backlight FPC comprising an annular FPC body and a leading-out terminal led out by the FPC body. The leading-out terminal and the FPC body are integrated into and the leading-out terminal encircles the FPC body. According to the backlight FPC disclosed by the invention, the annular FPC body and the leading-out terminal that is led out by the FPC body in an integrated manner and encircles the FPC body form the backlight FPC, so that the production materials of the FPC are saved, the production cost of the FPC is saved, and the reliability is high.

Description

technical field [0001] The present invention relates to the technical field of photoelectric display, and more particularly relates to a backlight FPC and a display device with the FPC. Background technique [0002] With the continuous improvement of intelligent ecosystems such as interconnection, intelligence, and cloud, the fields involved in display devices are increasing day by day, such as liquid crystal displays suitable for vehicles, military, and medical applications, and smart wearable devices. At present, most of the display devices in the display market are passive light-emitting products, and the backlight module provides the light source required for display. The existing backlight module generally includes LED light sets and FPC (flexible circuit boards). The power supply line is connected with the main board by FPC. [0003] With the development of technology and the intensification of market competition, the cost requirements of products are getting higher a...
